I was out today...chilly....combat trousers (with cycle clips) and an old knackered goretex jacket.....nobody spoke to me*, even though I waved to 3 cyclists.
I wear the same gear most of the time, all non cycling specific. The one nod to cycling are the leggings, but they are practical general wear too. My general wear errs on cycling friendly though, as I've always needed to jump on a bike as and when.
I am steering towards the 50s. I come from baggy neon clothing and combat military trousers and large flanell shirts for biking at the beginning of the 90s.
Nowadays for a proper workout and spin, I wear my all black (omg!) GORE BiB tights and functional jackets. And I never ever want to wear anything else anymore.
These rants always come from boomers that cant cope with today or progress. Presumably never had a proper workout in awesome bike specific clothing in their lives.
I recommend chilling at home after a good spin and putting on the dark side of the moon - but only on a proper vinyl player!
